Dev的GridView中如何自动生成行号

 1 public static void SetRowNumberIndicator(GridView gridView)
 2         {
 3             gridView.BeginUpdate();
 4             gridView.OptionsView.ShowIndicator = true;
 5             gridView.CustomDrawRowIndicator += new RowIndicatorCustomDrawEventHandler(
 6                 delegate(object sender, RowIndicatorCustomDrawEventArgs e)
 7                 {
 8                     if (e.RowHandle >= 0)
 9                     {
10                         int rowNumber = e.RowHandle + 1;
11                         e.Info.DisplayText = rowNumber.ToString();
12                     }
13                 }
14             );
15 
16             gridView.DataSourceChanged += new EventHandler(
17                 delegate(object sender, EventArgs e)
18                 {
19                     gridView.IndicatorWidth = 22 + gridView.DataRowCount.ToString().Length * ((int)gridView.Appearance.HeaderPanel.Font.Size);
20                 }
21             );
22 
23             gridView.EndUpdate();
24         }
